Technical Handbook 57
The device is supplied with many communication ports for connecting to a PC, modem,
networks etc.
In standard construction, the device is supplied with:
•
(JB) USB connection type B, for FW updating and parameter programming
•
(JA) RS232 Serial connection: maximum connection length 12m.
•
(JO) RS485 Serial connection with galvanic isolation; maximum connection length
under optimal conditions, 1200m. The 120ohm termination resistor is built-in; to
enable it, all you must do is connect pins 1 and 2 of the JO to each other. Shielded
cable with 120ohm impedance should be used (such as BELDEN 3105A Multi-
conductor-EIA Industrial RS-485PLT/CM).
•
(JS) RJ45 connector for connection to Ethernet networks 10/100.
•
CAN-BUS connection to the engine ECU and the additional optional modules (DITEL,
DITHERM, DIGRIN and DIVIT), with galvanic isolation. The 120ohm termination
resistor is built-in; to enable it, all you must do is connect pins 4 and 5 of the JO to
each other. It requires the use of a specific shielded cable (such as HELUKABEL
800571).
For details concerning the communications see the specific paragraphs and the document [3].
The RS232 JA connector (serial port 1) can be used for interfacing with an external device
provided with RS232 interface, such as, for example, a modem or a PC. The maximum length
of the connection should be no more than 12m.
The connection can be used for programming the parameters of the device through the
BoardPrg3 program, or for connecting to a supervising program such as SicesSupervisor.
For the functions and protocols implemented, refer to document [3]. See below the diagram of
